Description
Technical field
The utility model belongs to taximeter automatic Verification technical field, and in particular to a kind of taximeter inspection
Surely visual sense sampling system is used.
Background technology
Existing taximeter verifying process flow is such：After taxi enters calibrating station, sailed by verification worker guiding
On the verification table of upper taximeter verification system, and by fee register reading back to zero.Verification worker starts on verification table afterwards
Mileage calibrating installation, verification table starts to rotate with taxi front-wheel, the actual row of taxi that taxi verification system is collected
Distance is sailed to start to increase.Period verification worker pays close attention to taximeter reading always, when reading reaches default certified value, presses
RF remote-controlled collection key, collection signal is sent to taximeter verification system.Taximeter verification system is received adopts
After collection signal, current taxi actual travel rice number is recorded, with fee register read-around ratio compared with obtaining the actual mistake of taximeter
Difference, so as to judge whether taximeter error is qualified.
This kind of verifying process flow, taximeter mileage reading sampling is completed by human eye, has following asking using artificial sample
Topic：Firstth, people is digital to remote keying needs certain reaction time is pressed from fee register display screen is seen, according to data, people
The General reactions time be 0.3 second, this will cause certain systematic error.Secondth, people due to fatigue or external environment divert one's attention,
When fee register display screen numeral is beated, not necessarily can at once it is noted that the error that causes of such case be possible to can be very big.
Utility model content
The technical problems to be solved in the utility model is：A kind of taximeter calibrating visual sense sampling system is provided,
So as to reduce taximeter gauging error.
The technical solution of the utility model is such：
First, the utility model proposes such a taximeter calibrating visual sense sampling system, the system by
Image collecting device in taxi is constituted with pattern recognition device.The system is matched somebody with somebody with taximeter verification system
Set is used.The data acquisition device includes fee register fixture, and the fee register fixture is provided with wireless camera and for this
The rechargeable battery that wireless camera is powered, wireless camera is sent out the data of collection by wireless signal；Described image is known
Other device includes wireless signal receiver, host computer and radiofrequency launcher.
Wherein, the fee register fixture is removably mounted on taximeter, and wireless camera positive alignment is hired out
Car fee register display screen.
Image recognition software of the host computer equipped with the data of having the records of distance by the log for identifying fee register display screen.
Taximeter Visual Sampling calibration method is carried out using this system to comprise the following steps：
Step 1：After taxi enters the verification table at calibrating station, by taximeter reading zero；
Step 2：Fee register fixture is installed on taximeter, makes the wireless camera positive alignment on fee register fixture
Taximeter display screen simultaneously proceeds by IMAQ；
Step 3：Start the mileage calibration equipment on the verification table at calibrating station, verification table starts to turn with taxi front-wheel
It is dynamic, the actual mileage of taximeter verification system start recording taxi simultaneously, in taxi on fee register fixture
The image of the newest reading that wireless camera constantly shows taximeter display screen is passed by way of wireless signal
Return host computer；
Step 4：When the image recognition software system identification of host computer reaches default certified value to taximeter reading
When, software sends collection signal by radiofrequency launcher to taximeter verification system；
Step 5：After taximeter verification system receives collection signal, the current taxi of mileage calibration equipment will be recorded
Car actual travel mileage with by the fee register read-around ratio of wireless camera collection compared with obtaining the actual mistake of taximeter
Difference, so as to judge whether taximeter error is qualified.
Taximeter display screen is shown that numerical sample is automated by the utility model using image recognition technology, can be with
The error for avoiding these human factors from causing, mitigates the work load of staff, and improves calibrating efficiency.

Description of reference numerals：1- taximeters, 2- fee register fixtures, 3- wireless cameras, 4- rechargeable batteries, 5- without
Line signal receiving device, 6- host computers, 7- radiofrequency launchers, 8- taximeter verification systems.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the system is made up of the image collecting device in taxi and pattern recognition device.This is
System supporting with taximeter verification system 8 is used.Described image harvester includes fee register fixture 2, fee register folder
Tool 2 is provided with wireless camera 3 and the rechargeable battery 4 for being powered to the wireless camera 3, and wireless camera 3 is by wireless
Signal is sent out the image of collection；Described image identifying device includes wireless signal receiver 5, host computer 6 and radio frequency hair
Emitter 7.As shown in Fig. 2 fee register fixture 2 is removably mounted on taximeter 1, the positive alignment of wireless camera 3 goes out
Hire a car the display screen of fee register 1.Image recognition software of the host computer 6 equipped with the data of having the records of distance by the log for identifying fee register display screen is simultaneously
And host computer 6 realizes signal transmission by video transmitter 7 with taximeter verification system 8.
Embodiment 1：
As shown in figure 1, after taxi enters calibrating station, verification table is reached by verification worker guiding.Then verification worker will valuate
Device fixture 2 is arranged on taximeter 1.Wireless camera 3 starts to carry out the reading display screen of taximeter 1 afterwards
IMAQ, and the host computer 5 that image is passed back on verification table will be gathered.The mileage calibrating that verification worker starts on verification table afterwards sets
Standby (typically a set of tape measure equipment, for recording taxi front-drive distance), taxi front-wheel starts with verification table
Mileage calibration equipment start to rotate, wireless camera 3 constantly passes the image of the newest reading of taximeter 1 back host computer
5.When the software systems of host computer 5 recognize the mileage reading of taximeter 1 reaches default certified value, software is sent out by radio frequency
Emitter 7, collection signal is sent to taximeter verification system 8.Taximeter verification system 8 receives collection signal
Afterwards, the fee register read-around ratio of the current taxi actual travel rice number for mileage calibration equipment being recorded and collection is compared with being hired out
The actual error of car fee register, so as to judge whether the error of taximeter 1 is qualified.At the end of verifying process flow, on verification table
Mileage calibration equipment by radiofrequency launcher 7 to taximeter verification system 8 send calibrating END instruction complete calibrating.
Certainly, it is more than concrete application example of the present utility model, the utility model also has other implementation methods, all
The technical scheme formed using equivalent or equivalent transformation, is all fallen within the protection domain required by the utility model.
